Frequently Asked Questions
What are the common rules for signature uploads?
Signatures must be on white paper with black or blue ink. The file size is typically much smaller than a photo, often between 10KB and 20KB.
How do I make my scanned signature look clearer?
Use the 'Contrast' or 'Brightness' slider in our signature tool to whiten the background and make the ink stand out, ensuring it passes automated portal checks.
Can I crop just the signature from a full page scan?
Yes. Our signature resizer includes a precision cropper to help you isolate the signature area perfectly.
What happens if my signature file is too large?
Portals will show an 'Invalid File Size' error. Use our target KB slider to force the file size below the required limit (e.g., 15KB).
Do I need to sign in uppercase?
No. You should sign in your natural running hand. Full block letters (UPPERCASE) are often rejected as signatures on legal documents.
Is the signature data uri safe?
All processing is local. We don't log or store your signature scan, ensuring your digital identity remains secure.
Can I convert my signature to a transparent PNG?
For exam forms, a white background JPG is preferred. For digital documents, you can use our 'Clear Background' toggle to generate a transparent image.
How many DPI should the signature scan be?
Aim for at least 200-300 DPI for a clean scan. Our tool will then handle the final pixel dimensions required for the upload portal.
Can I sign on my phone screen?
Yes. Our signature page includes a 'Touch Canvas' where you can sign directly with your finger or a stylus and download the result immediately.
What if the signature is too faint?
Use the 'Darken' filter in our tool to boost the ink visibility before downloading.
